MECHANISM FOR FORMING DOUBLE THREADS UPON THE SOLES 0F STOCKINGS MANUFACTURED ON I CIRCULAR-KNITTING MACHINES.

SPECIFICATION formingpart of Letters Patent No. 761,632, dated May 31, 1904:,

Original application filed June 4, 1903, Serial No. 159,996.

To all -whom git may concern.-

Be it known that I, HARRY A. HOUSEMAN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of companying drawings, which form a part of this specification.

' A circular-knitting machine with which my improved mechanism is adapted to be used is clearly shown and described in an application filed by me June 4:, 1903, Serial No. 159,996, of which this application. is a division. It is therefore not necessary in this application to describe'the machine generally. I therefore have in the accompanying drawings and in the following specification illustrated and der on line2 2, Fig. 1.

scribed specific parts forming the subject of this invention.

In the accompanying drawings, Figure 1 is a partial plan view of needle-cylinder and thread-guide. Fig. 2 is a sectional elevation Fig. 3 is an enlargedside detail. Fig. A is a side elevation. Fig. 5 is a rear elevation.

Q is the ordinary thread-guide.

Q is the thread-guide for the supplemental thread for the sole. This thread-guide is pivotally attached to the stud q and normally held in active position by the spring This thread guide has the tailpiece g resting against the end Q3 of the pivoted lever said lever having at its opposite end the roller (1 Upon the top face of the cam-cylinder F is the raised ledge R, having at one end the inclined face 1". The normal position of the roller 9 of the lever is such that it is within the line of the outer portion of ledge R and the thread-guide Q under the action of the spring q in action. When in the operation of the machine the roller Q5 reaches the face 0, it is carried outward to the outer end Q, into active position.

Divided and this application filed July 17, 1903. Serial No. 165,974. (No model.)

of the ledge R, the lever q turning on its pivot and moving the guide Q out of action against its spring q. When the roller (1 passes the ledge R, the roller drops from the outer face of the ledge and the spring returns it to its original position and the guide By arranging the position and extent of the ledge R so that it is upon the needle-cylinder at the point where the face of the foot is being formed the supplemental thread will be automaticallythrown in and out of action in passing to and from the sole portion of the foot. In order to maintain this guide Q out of action when those portions of the stocking other than the foot are being formed, I use the following mechanism: The lever (f has the projecting portion 8, against which rests the cam s at the end of the lever S, pivoted in the friction bearing .9". This lever has also .the notch 1 with which the pin 8, acted upon by the spring 8 is adapted to drop when the lever S is rocked. By rocking the end of lever S the cam .9 acts upon the portion 8 of lever (1 moving the roller Q5 outward and throwing the thread-guide Q out of action and the roller 9'' out of influence of the ledge R, the spring-pin s acting as an additional holding device. I can operate this lever S automatically by means of the cams T T, which are secured to the pivoted lever T acted upon by the lever T, which is vertically movably supported. In the operation of the machine the position of cams T T is such that the end of lever S passes between them, and by elevating the lever T and lever T so as to bring the cam T in line with the end of lever S, the lever S is released from the lever (1 while if the lever T and lever T be depressed, so that the cam T is in line with the end of lever S, the lever S is operated to move the lever q to throw the thread-guide out of action. The upward movement of lever T may at the appropriate time be given by any desired mechanism. I will now describe one set of mechanism. I use in this machine the same mechanism for operating the clutch-rod H to shift from rotary motion to reciprocating motion of the cam-cylinder as in the machine of my Patent No. 538,518 and the same mechanism to rotate and reciprocate the cam-cylinder as is set out in my application, filed July 17, 1903, Serial No. 165,97 3, and it need not here be described in detail. Upon the shaft 200, which determines the operation of such mechanism, I place the cam-roller Z, having the high portion Resting upon the roller Z is the roller 2, connected to the part .2 of the lever T so that when the shaft is operated on and off the heel and toe the lever T is raised and depressed and the thread-guide Q thrown out of and into action. To throw the thread-guide Q out of action in going on the leg and maintain it out of action during the formation of the leg, I use a pattern-chain Y upon the sprocket Y on shaft Y A projecting arm Y from lever T rests upon the patternehain. Pivoted to the arm Y so as to be in line with shaft Y is the long arm Y", having the notched end Y. When a high lug Y upon the chain (which is arranged to pass at the time of going on the leg) strikes the end of the arm Y, it lifts the lever T and lever T moving guide Q out of action. This movement lifts the arm Y, so that when the lug Y passes it the arm Y drops upon the shaft Y holding the lever T up and the guide Q out of action. When the leg has been completed, a side lug Y upon the chain strikes a tailpiece of arm Y, swinging it free from shaft Y and allowing the arm Y to drop and lower the lever T and bring the thread-guide Q again into action.

In order to prevent the arm Yfrom acting when the lever T is lifted by the action of cam-roller Z, I use the following mechanism: 100 is a pivoted bar having the pin 101, the bar'being in such position that the arm Y will strike the pin 101 before the arm Y' alines with shaft Y so that normally on the lift of the lever T the arm Y is inactive. hen the lug Y strikes the lever T it also lifts the bar 101, so that the arm Y can swing so that the notched portion rests on the shaft. In order to prevent. the action of bar 100 and pin 101 when the lug Y lifts the lever T", I construct the bar 100 so that it as well as arm Y is in line with the lug or high link Y, so that in the lifting of the arm Y by the high link the bar is moved, so that the arm Y can swing in line with shaft Y uninfiuenced by the bar 100 or pin 101. When the arm Y* is in position on the shaft, the pin 101 rests in a detent y in the arm Y". The bar 100 is released by the lug Y Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is r 1.
